I am building my own PC, and I am interested in getting Windows 7 (64 bit) with a student discount. On the Microsoft site, it is labeled as an upgrade; does that mean I can't just purchase it and install on my brand new PC? And if I do download it on my current computer running Vista (but NOT install it on my current PC), could I use a flash drive or hard drive to install on my new PC?
I have looked around on the Web and here on SU and have some different answers, but I want to be sure before purchasing. Thanks!
